Isomerism

Define Structural isomerism Define Stereoisomerism Define   E–Z isomerism is a form of stereoisomerism resulting from the restricted rotation about the planar carbon=carbon double bond. Students should be able to: • define the term structural isomer • draw the structures of chain, position and functional group isomers • define the term stereoisomer • draw the structural formulas of E and Z isomers. Assessment

Organic reaction mechanisms (nomenclature)

Reactions of organic compounds can be explained using mechanisms. Free-radical mechanisms: • the unpaired electron in a radical is represented by a dot • the use of curly arrows is not required for radical mechanisms. Students should be able to: • write balanced equations for the steps in a free-radical mechanism.   Other mechanisms: • the formation of a covalent bond is shown by

Organic nomenclature

Organic compounds can be represented by: • empirical formula • molecular formula • general formula • structural formula • displayed formula • skeletal formula. The characteristics of a homologous series, a series of compounds containing the same functional group. IUPAC rules for nomenclature. Students should be able to: • draw structural, displayed and skeletal formulas for given organic compounds • apply IUPAC
